Change icon size for "small" from 36px to 32px
Very few icon themes and apps (including Xfce apps) provide icons for 36px. Scaling the icons to 36px made them blurry in Appfinder. This should fix that an use the native 32px icons, making them a bit sharper/clearer.
Please let me know if I need to make changes anywhere else. I tested it out and it looks okay to me in regular (list view) and icon view. Thanks!
